Re: Fwd: [Haskell-cafe] Data.Tree.Zipper in the standard libraries

Hi Krasimir,

What is the strong justification for adding this to the base library? Is there some particular reason that it can't be done outside of base, or is there some particular need that makes this code desirable in the base libraries? Could it be added as a separate library on hackage, worked on for a while, and then merged into the base latter if appropriate?

'containers', not 'base'. But still, I think it should stay in a separate package. Someday Data.Tree may be removed from the more-used containers too. (do we know who does use Data.Tree, btw?) -Isaac
